THOMAS BARBER, or FLATBUSH, new YORK.

BOILER-FEEDER AND ALARM.

SPECIFICATION forming part of Letters Patent No. 319,662, dated June 9, 1885.

Application filed February 28, 1885. (No model.)

T 0 all whom it may concern.-

Be it known that I, THOMAS BARBER,,a citizen of the United States, residing at Flatbush, in the countyof Kings and State of New York, have invented new and useful Improvements in Boiler-Feeders and Alarms, of which the following is a specification.

This invention relates to a boiler-feed in which, by the action of a float, steam is admitted to a pump when the water gets low, and the pump is set in operation until the water has reached the mean water-level, when the steam is shut off from the pump. If'the water gets low and the pump is not started, from some unforeseen cause, steam blows off through a pipe and an alarm is given.

The novel and peculiar construction of my feed mechanism and detecter is pointed out in the following specification and claims, and illustrated in the accompanying drawings, in which Figure 1 represents a sectional side view of a steam-boiler containing my feed and detecter mechanism. Fig. 2 is a front view of the boiler, showing the connection of the feed and detecter mechanism with the pump. Fig. 3 is a transverse section of the principal working parts of my feed and detecter mechanism on a larger scale than the previous figures, the line :r 00, Fig. 4, indicating the plane of section. Fig. 4 is a face view of the same. Fig. 5 is a a horizontal section in the plane 3 y, Fig. 4.

Similar letters indicate corresponding parts. In the drawings, the letter A designates a steam-boiler, which may be a plain cylinder boiler or a tubular boiler, the boiler shown in the drawings being a plain cylinder boiler. In the interior of this boiler is placed a chamber, B, which connects at its lower end with a pipe, 0, and at its upper end with a pipe, D. These pipes extend to the outside of the boiler, and they support the chamber B in the desired position in the interior of the boiler. The pipe 0 connects with the steamehest of the feed-pump E, Fig. 2, and serves to supply steam to this pump whenever it is desirable to start the same. The pipe D forms the alarm-pipe, and it leads to the office of the building in which the boiler is situated or to any place where the alarm is to be given.

The chamber B is by preference made oblong, but it may be made in any other conused in a tubular boiler.

venient form or shape suitable for my purpose. It is provided with a transverse partition, (I, Fig. 3, a lateral part. b, below this partition, and a longitudinal channel, 0, leading to and communicating with the pipe 0. Above the partition a the chamber B is provided with two lateral ports, d e, and a longitudinal channel, f,leading t0 and communicating with the pipe D.

The chamber B, which is stationary, fits into a valve, F, which is movable longitudinally upon the exterior of the chamber, and which is provided with two lateral ports, 9 h, the port 9 being situated on one and the port it being situated on the opposite side of said valve, (best seen in Figs. 3 and 4;) and since it is desirable that these ports, particularly the port g, shall be narrow and at the same time of sufficient area to admit the requisite quantity of steam to the pump E, the chamber and the valve are made oblong, as above stated, so that the port 9 can be made of the required shape and area. i

The valve F connects by a bifurcated or yokeshaped link, G, with a lever, H, which has its fulcrum on a standard, I, and to which is secured a weight, J, and a float, K. (See Fig. 1.) The standard I is secured in the interior of the, boiler, either upon one of the braces, as shownin the drawings, or upon one of the boiler tubes or fines, if the apparatus is The lever H has its fulcrum on a pivot which has its bearings in the standard I and extends through the lever, and said lever is supposed to about balance the weight of the yoke G and of the valve F without the weight J and the float K; and when the water in the boiler sinks down the valve F is carried down by the action of the weight J and the float Kto the position shown in Fig. 3, the port 9 is opened, and steam is admitted to the pump E, so that an additional supply of water is injected into the boiler. But if, from some unforeseen cause, the pump should fail to work, the water in the boiler will sink down and the valve will be depressed, so as to bring the port h of the valve opposite the port d in the chamber, and as soon as the valve reaches this position steam blows off through the pipe D and an alarm is given.

The weight J is made to weigh about ten pounds, and the float H is made of such asize that it buoys up about twenty pounds, so that when the water sinks the valve is moved down by the weight J, and when the water rises the weight, together with the valve, is raised by the buoyancy of the float.

\Vhat I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the chamber 13, having the lateral port b and the pipe 0, for connecting with the pump E, with the valve F, having the lateral port g,and movable lengthwise upon the exterior surface'ot' the chamber, the lever H,conneeted with the valve,and the float K,eonnected with the lever, substantially as described.

2. The combination, with the valve F and its port h, ofthe chamber B, the port Z,formed in this chamber, the alarm-pipe D, communicating with the chamber, the lever H, connected to the valve, and the float K, substantially as shown and described.

3. The combination, with the valve F and its ports 9 h, of the chamber B, the partition a formed in this chamber, the ports b d on opposite sides of this partition, the pipe 0, leading from the lower part of said chamber to the pump E, the alarm-pipe D, communicating with the upper part of the chamber, the lever H,'conneeted to the valve F, and the float K, substantially as shown and described.

In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.
